GPS Diagnostic View
GPS Diagnostic View, which is only available when a GPS Receiver is attached to your 1100 Series, shows
a sky chart and numerical data from the GPS receiver. The sky chart shows the location of each visible GPS
satellite with its satellite number and a signal strength bar. A dark gray bar indicates that the satellite is
being used to determine your current position. A light gray bar indicates that the satellite is being
monitored, but is not yet being used.
This view also reports the current position, local time and date, and other numeric information. The current
GPS Fix Type is reported as No Fix, 2D Fix, 3D Fix, or Enhanced. An Enhanced fix has been augmented using
information from WAAS, EGNOS, or MSAS. A 3D or Enhanced Fix is required for navigation. HDOP (the
Horizontal Dilution of Precision) is a GPS system parameter which depends on the current satellite
configuration. HDOP is used to calculate the Estimated Position Error.
